SPECIFICATION forming part of Letters Patent No. 381,067. dated `April10, 18238.l 'Application mea september 6,1857. serialNo. 245,919. kNomeer) F To all whom it may concern:

Be it known rthat I, HENRY ing at New Orleans, in the parish of Orleansand State of Louisiana, have invented certain new and usefulImprovements in' WaterFlters; and I do declare the following to beafull,

' such aswill enable othersfskilled in lthe art to i vview of the same',.with the upper pure-waterv 'i duction of sand-.or thelike.

which it appertains to make and use the same.

This invention relates tofilters; and the improvements will be'full'yunderstood from the following description and claims, when taken inconnection with the annexed drawings, in which- Figure l is aperspective View of my improved filter. Fig. 2 is a vertical sectionalchambers broken away; and Fig. 3 is a verticalfsectio'nal View kof oneof the' pure-water chambers, showing ythe pipes for connecting the samewith the filtering-chamber.

Referring by letter'to the said drawings, A

indicates the main chamber, whichfmay be of.

any suitable capacity and form, and into which the Water to be filteredis introduced,'as will be 'presently explained. This `chamber is relduced to a concentric water-chamber, a, by placing therein a centralchamber, B, which is filled with sand or other filtering material.

The chamber B is composed of a perforated shell, theroof of which isalso perforated, asV 'shown at b.

The concentric water-chainber'a is provided with an inlet-aperture, c,for the introduction of yimpure water, and also an ap.

erture, d,for the outlet of mud and sediment. The centralfiltering-chamber, B, is also provided With a cappedaperture, e, fortheintro- It will thus be seen that when it is desirable to clean out themain water-,chamber a it is only necessary to remove the cap from theopening d and let water in under pressure through the aperture c, whenthe mud will be effectually removedy and expelled therefrom.

v D is an auxiliary filtering-chamber, which is arranged above thecentral basechamber, B, and has a capped opening, f, for theIintroduction of sand or the other filtering-material,as
